Mixture the Annex Fuel According to the Table Map

Adding a fuel additive or fuel treatment in your fuel is one way that will help you save money on gas. Annex Fuel, for example, will help lower the burn rate of your fuel creating improved gas mileage, less carbon buildup, lower emissions, and more horsepower. Listed below are the steps on how you can use this fuel treatment effectively and save money on gas.

Record the usual MPG. Before you use the Annex Fuel it is best to record first the KPL (Kilometer per Liter) that you get without the fuel treatment. For more accurate KPL, calculate it manually. It is also recommended to fill your tank full and empty it before the next fill up.

Calculate the KPL manually. Record the odometer reading at the time you will fill up the fuel tank and also at the time you will have the next fill up. Get the difference of the two odometer reading and that will give you the total miles you traveled. Make sure that you know also the amount of fuel you put in your tank. To get the KPL, divide the total Kilometers you traveled by the total amount of fuel you put in your tank. You may do this test two or three times if you like so you have different records of KPL that resulted from not using a fuel treatment and see if they varies.


Compare the results. If you get more KPL by using Annex Fuel than by not using it, then you definitely save money on Fuel. Annex Fuel should save you $10 to $20 every fill up. To learn more about this product, click this link.


Items to be aware of when comparing fuel economy:

    • Different drivers usually obtain different results
  • KPL may vary due to terrain, loads and weather conditions
  • KPL may vary between fuel brands
  • KPL may vary when using winter blend vs. summer blend fuels
  • City mileage and highway mileage will differ – compare similar trips
  • For the most accurate results, calculate KPL manually


How Annex Fuel Works

Annex brings multiple components together in a unique way to make it the most comprehensive fuel treatment on the market among all other engine fuel additives, whether for Petrol or Diesel!


Annex Fuel is a fuel stabilizer. Once fuel is made, just like any oil-based product, it has a tendency to begin separating. As it separates, it loses some of its efficiencies. Xtreme Fuel Treatment stabilizes the fuel, keeping this breakdown from happening for longer periods of time.The benefit of this is that stored fuel will have a much longer shelf life. This is especially important for boat storage, lawn movers, weed eaters, quad bikes jet skis or any other seldom used, engine powered machinery.



Even though your fuel tank is sealed, between heat creating condensation as well as the oxidation process, you cannot avoid getting water in your fuel. Annex Fuel contains a demulsifier which helps remove water from fuel due to this condensation and other sources of water. Why is this important? Water can be very harmful and costly to an engine and water can also be a major contributor to fuel injector failure.



Modern, high-tech, fuel injected engines have very tight tolerances. This means that they function very precisely and there is little to no room for even a tiny particle of dust or dirt without impacting performance. Annex Fuel contains detergents that keep your engine clean and remove harmful deposits from fuel pumps and injectors. Continual use of Annex Fuel will maintain peak performance in your engine and the function of all of these important parts. 


Annex Fuel contains an oil-soluble organo-metallic compound which functions as a “burn rate modifier” and a “catalyst” to lower the ignition point of fuel by several hundred degrees. This creates a longer burn time, allowing your engine to burn much more of the injected fuel. Lowering the ignition point of the fuel, and providing a longer burn time for the combustion process, not only means a more complete burn, but also means that more fuel powers the engine and little if any goes out the exhaust


Annex Fuel contains a polymerization retardant and dispersant to help prevent and reverse sludge buildup in your fuel which can and does clog filters. This is especially important in diesel fuels.



Any time you put liquids and metals together, add oxidation, heat, and condensation, you are bound to get rust and corrosion. This is what happens in your fuel tank, however,Annex Fuel contains rust and corrosion inhibitors to minimize corrosion in fuel tanks and delivery systems. 

Look at the difference between these engine valves before and after treatment.


Annex Fuel provides lubrication for pistons, fuel pumps, and injectors, reducing friction and prolonging the working life of the engine parts. Inadequate lubrication of parts from today’s fuels can result in premature failure of engine parts and therefore costly replacement and repair.


  • Combustion Catalyst – Extends the burn rate of fuel during combustion to provide a more complete burn, resulting in increased fuel mileage, fewer harmful emissions and less carbon buildup on engine parts.
  • Detergents – Removes harmful deposits from fuel pumps, injectors and throughout the fuel system.
  • Lubricants – Provides lubrication to pistons, fuel pumps and injectors, reducing friction and prolonging the working life of the engine.
  • Fuel Stabilizer – Prolongs the life of stored fuel; ideal for seldom used equipment.
  • Polymerization Retardant & Dispersants –Reduces sludge buildup in fuel which can plug filters.
  • Rust and Corrosion inhibitor – Prevents tank and fuel system corrosion caused by oxidation and condensation.
  • Demulsifier – Helps remove water from fuel. 


  • Burn rate modifier lowers the ignition point of the fuel giving a 50% longer, cleaner burn in the engine. 
  • Burning more of the fuel in the engine increases mileage and performance while reducing un-burned emissions
